BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be further described in combination with the accompanying drawings and the detailed description:

FIG. 1 shows an overall structural diagram of the invention.

DETAILED DESCRIPTION

As shown in FIG. 1, a hybrid driving snow sweeper comprises a snow sweeping impeller 3. The snow sweeping impeller is mounted on an impeller shaft 31, and the impeller shaft is driven by a motor. The motor comprises a DC motor 1 and an AC motor 2. The DC motor and the AC motor are connected with a control panel 4. The control panel is connected with a switch 41. The control panel is connected with wires of battery power supply and AC power supply. The AC power supply is connected with a plug 21. The control panel controls the operation of the DC motor or the AC motor so as to drive the impeller shaft. The DC motor 1 and the AC motor 2 are located at both axial sides of the impeller shaft 31.

The battery power supply comprises several lithium battery packs which are mounted in a battery positioning frame 12. The DC motor is a brushless motor which is connected with a brushless controller 11, and the output shaft of the brushless motor is linked with the impeller shaft 31 directly via a coupling.

The impeller shaft 31 is connected with a big belt pulley 32, and the output shaft of the AC motor is connected with the big belt pulley via a belt. A clutch protecting mechanism, which protects a clutch and a clutch disc, is provided between the big belt pulley and the impeller shaft.

The first step is to pack a single battery pack or a plurality of battery packs into the battery positioning frame and turn on the switch, and at this point, the machine begins to work normally; the second step is to connect the machine with AC via an AC plug when the DC battery finishes discharging or the operator wants to connect the machine with AC, and the system automatically switches to preferably select AC power supply for operation.

When the power supplies of the DC motor and the AC motor are effectively switched on simultaneously, the switch is turned on, and the control panel controls the operation of the AC motor; when the DC motor works, after the power supply of the AC motor is effectively switched on, the control panel controls to switch to the operation of the AC motor; and when the DC motor works, if the battery power supply is low, and the power supply of the AC motor is effectively switched on simultaneously as well, the control panel controls to switch to the operation of the AC motor.

In the invention, the hybrid uses a double-motor mode so as to ensure through a conversion mechanism that in the process of using the DC motor, the AC motor does not work, or when the AC motor works, the DC motor does not work, and ensure a mutually switchable working mode between the hybrid AC and DC.

The motor used by the hybrid can be a combination mode of brushless motors, a combination mode of magnetic steel motors, a combination mode of series-excited motors, a combination mode of induction motors as well as a combination mode of crossing among motors.

In addition, when the AC motor works, the DC motor can automatically generate electricity and supply power so as to ensure the operation of other accessories.
